Used to be a great firewall...but not anymore by fwt1111683
Jun 24, 2012

Years ago, ZoneAlarm was a great product. But ever since Checkpoint bought Zone, ZoneAlarm has consistently gone downhill to the point where it can no longer compete with the competition. If you don't have a firewall, get Comodo. If you're using ZoneAlarm, dump it and get Comodo.

I liked Zonealarm when it first came out, but now this version likes to run your computer for you and has much less user control over what comes and goes and seems a bit bloated. Too complicated and has to be 'watched'. I also note it did not 100 pass the 'stealth' tests I usually test firewalls with. There are other ones that are more basic.

I had ts version of Zone Alarm Free, right where Id it. ings, the training, etc ... Then I got the updated version. Big and sorrowful mistake on my part. I thought, maybe it's just the free version, so Ii tested some of the Pro trials and it was all the same. The most important feature of any good Firewall program is the ability to halt ALL network traffic. Zone Alarm doesn't allow this anymore?
I dropped Zone Alarm 12 years ago because they made updates mandatory in the free version. I heard from a trusted source that their policies had changed. And for a while it looked like they had.
So once again, I have to boycott all Zone Alarm products from all the computers I work on.
Do yourself a favor and try Personal Firewall instead.
